Absolutely fascinating! I love London and must have nearly two dozen books about every aspect of the city. This is a beautiful book to look at and read. It lightly touches on different stories to do with the Zone 1 (the heart of London) tube stations- just enough information to give the already curious a springboard for further investigation. This is the kind of book I really enjoy, one that introduces you to something that feeds a burning obsession. I can't wait to investigate more!
